Abstract:

An air conditioner (1) in which indoor temperature can be detected accurately even in the case of an indoor unit in a thermostat-off state while suppressing abrupt lowering of supply air temperature in an operating room. The air conditioner (1) comprises a plurality of indoor units (3a-3d), an outdoor unit (2), and an outdoor control section (25). Each indoor unit (3a-3d) comprises a room temperature thermistor (33a-33d), an indoor heat exchanger, an indoor fan (32a-32d) and an indoor control section (34a-34d). The outdoor unit (2) comprises an outdoor heat exchanger and constitutes a refrigerant circuit with the plurality of indoor units (3a-3d). The indoor control section (34a-34d) makes a decision whether the conditions for starting room temperature monitoring by the room temperature thermistor (33a-33d) are satisfied or not and drives the indoor fan (32a-32d) if room temperature is monitored at the time of thermostat-off of heating operation. The outdoor control section (25) selects a specified indoor unit from among the plurality of indoor units (3a-3d) and transmits a signal concerning permission of room temperature monitoring to the indoor control section of a selected indoor unit. Furthermore, the indoor control section (34a-34d) makes a decision whether the room temperature monitoring is performed or not based on that signal and the conditions for starting room temperature monitoring.
